As the hours pass I get used to the motion of the train, the heavy wheels clacking in their grooves, the industrial hum under my seat. Dusk softens the sharp points of trees outside my window; the sky slowly darkens, then blackens around an orb of moon. Hours later, a faint blue tinge yields to the soft pastels of dawn, and soon enough sun is streaming in, the stop-start rhythm of the train making it all feel like still photography, thousands of images that taken together create a scene in motion.
